Attic Insulation


Boost Energy Efficiency and Save Money: Upgrade Your Houston Home with Attic Insulation!

Attic insulation is one of the most important things you can do to upgrade the energy efficiency of your Houston area home.
Heating and cooling accounts for 50 to 70% of the energy usage in the average American home. Inadequate insulation and air leakage are leading causes of energy waste in most homes.  Air Specialist offers blown-in fiberglass insulation services.  Adding fiberglass insulation above minimum requirements helps increase energy savings, provides greater noise control, and controls moisture which helps your Houston area home and roof last longer.

Benefits of Blown-In Fiberglass Insulation

  • Adjustable – Easily control the level of insulation you will need thus varying the R-value, i.e. blow in so many inches for an R-value of 15, and so many more inches until you have an R-value of 49. 
  • Made of Virgin Materials – Reduces the chances of allergies 
  • Tighter Fit and Seal – Blown into tiny crevices, direct around existing corners, beams, or wiring. 
  • Fast and Clean – Material is mixed and expanded inside a self-feeding integrated machine, providing easy clean-up and little dust production. 
  • Extremely Energy Efficient – Keeps its R-value over time because it is does not settle and is moisture-resistant to prevent fungus or mold growth.

How Insulation Works

  • To maintain comfort in your home, the heat lost in the winter must be replaced by your heating system and the heat gained in the summer must be removed by your air conditioner. Insulating ceilings decreases this heat flow by providing an effective resistance to the flow of heat. 
  • Heat flows naturally from a warmer place to a cooler space. In winter, heat flow moves directly from heated living spaces to adjacent unheated attics, garages, or to the outdoors; or indirectly through interior ceilings, walls, and floors – wherever there is a difference in temperature. During the cooling season, heat flows from outdoors to the house interior.

R-Values for Enhanced Home Energy Savings and Comfort

Insulation is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value of thermal insulation depends on the type of material, its thickness, and its density. In calculating the R-value of a multi-layered installation, the R-values of the individual layers are added.

The map and chart below show the DOE recommendations for your area. State and local codes in some parts of the country may require lower R-values than the Department of Energy recommendations, which are based on cost effectiveness.


In the greater Houston and surrounding areas (Zone 4), the recommended insulation level for different areas of the house are as follows:

Gas, heat pump or fuel oil systems:
Attic: R-38
Cathedral: R-38
Wall: R-13
Floor: R-13
Crawl Space: R-19
Slab Edge: R-4
Interior Basement: R-11
Exterior Basement: R-4

Electrical furnace system: 
Attic: R-49
Cathedral: R-38
Wall: R-18
Floor: R-25
Crawl Space: R-18
Slab Edge: R-8
Interior Basement: R-11
Exterior Basement: R-10

Additional Benefit: Increased Home Value!

Adding fiberglass insulation is easy and can increase the value of your Houston home. By raising the levels of fiber glass insulation in your home, you can make your home more valuable because of its increased energy efficiency. And when it comes time to sell your home, it may be more valuable in the marketplace.

Insulation is an investment that pays for itself many times over. The initial cost to install insulation are typically recouped in three to seven years depending on how much more you add. And, fiberglass insulation continues to save energy and help lower bills for the life of your Houston area home.
